Model No. MEA-0001 · Atomic Absorption Spectrometers

Direct Mercury Analyzer with Thermal Decomposition and Amalgamation

热分解金汞齐化直接测汞仪

Fish, rice, soil and mine tailings can be tested for mercury in about five minutes with no acid digestion at all. Weigh 10–500 mg of solid, liquid or slurry, combust at up to 750 °C and trap mercury on gold before detection, with an absolute limit of 0.001 ng. Choose absorption or fluorescence detection to suit your levels.

Measurement range: 0.05–1000 ng
Detection limit: 0.001 ng absolute
Sample types: solid, liquid, slurry
Sample mass: 10–500 mg
Measurement time: approximately 5 min
